FRANK A. IIEWIS, OF PORTER TOWNSHIP, VAN BUREN COUNTY, MICHIGAN 7 ASSIGNOR OF ONE-HALF OF HIS RIGHT TO GILENS B. LEWIS..

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 224,094, dated February 3, 1880.

` Appncation inea August 25, 1879.

To Vall whom it may concern Be it known that I, FRANK A. LEWIS, of Porter Township, VanBuren county, State of Michigan, have invented a new and useful 5 Improvement in Coupling Cars, of which .the

` following is' a specification.

My invention is an improvement in earcouplings.

It consists of a hinged lever, with a coupro lin g-pin locked thereto, adapted to swing about a horizontal axis in the upper wall of a drawhead, said lever being moved automatically by contact ot' the coupling-link with the couplin g-pin, and, being released, drops by gravity I within the links slot, as will be hereinafter fully described.

In my drawing, the ligure is a sectional view, showing the several parts of the invention and the operation ot' the same.

zo Similar reference-letters denote like parts.

Referring to drawing, B is the draw-head or bumper ot' a railroad-car, having a V-shaped or flaring cavity formed within it forV the reception of the coupling-link. A slot is cut in z 5 the upper wall of the draw-head, with its front and side walls vertical and its rear wall beveled rearward. A

ct is a lever or cap hinged or pivoted to the draw-heads sides near the front, which, when 3o 'in its seat, rests horizontally on the upper surface of the said draw-head. On the upper side of the lever a is a hood or capping, D,

inclosing a tongue riveted thereto by rivet e.

C is the coupling-pin,tbrmed with a flanged 35 head, and having an annular groove to receive the tongue g.V

In the bottom Wall of the draw-head is a notch to receive the end ot' the coupling-pin when in position. 4o Between the lower surface of the tongue g and the upper surface of thehinged lever ct is an elastic cushion, f, intended to take a part of the shock received upon the coupling-pin as the draw-heads separate in the act of coupling. A 45 The tongue g, when riveted in the cap or hood D, said cap being secured to lever a, together with the annular' groove, serves the purpose of a lock to hold the coupling-pin C as a part of hinged lever a, so that when the coup- 5o ling-link enters the draw-head it comes in contact with the coupling-pin and throws it backward and up with the hinged lever, as shown by the dotted lines in the drawing. When. the link has moved back of said pin the weight 5 5 of the lever causes the pin to fall within the links slot. After the tongue gis Xed in the cap or hood D with the rivet, the said cap or hood is placed upon the hinged lever a, with the-tongue g in the annular groove ofthe coup- 6o ling-pin, and secured to said hinged lever with nails or screws. Then the link is drawn upon it comes in contact with the pin C, and causes the iiange of the head to bear against the tongue g, and bears the said tongue down upon 65 the cushion f. l

I am aware of the patent to Merkle and Merkle,No. 142,713,in which is shown a hinged lever and a coupling-pin hinged thereto, and to suchI make no claim. 7o

What I claim as new, land desire to secure by Letters Patent, is-

A In combination with a draw-head and couplin g-link of a car-coupling, the hinged lever a, pin C, provided with annular groove, and the 75 lockin g device for said pin with said lever, composedot the hood D and tongue g, as and for the purpose set forth.
